While her big brother wasn't looking, the innocent little sister he once knew secretly mastered the art of masturbation... Lately, she's been absorbed in her new skills, acting awkward around him—but in truth, she's only gotten better. When her brother secretly peeks at her, she suddenly attacks him. Even as she resists, her pussy is slick and wet, and he forces a creampie. The sister screams, "Quit being so noisy—let me join in too!"—and though shocked, he can't help but respond. He pulls his beloved sister close, embracing her with his hard cock, pouring his love into her. Though she cries, "Not inside my vagina!", she quickly forgets her own words.
